Аннотация

Studies on the mechanisms for deformation of solid surface layers are analyzed based on the notions of physical mesomechanics. It is concluded that peculiarities of a crystalline structure of the solid surface determine specific deformation mechanisms evolving in surface layers of a loaded material at micro-, meso-, and macrolevels. Incompatibility of surface-layer deformation with that of a crystalline sublayer is responsible for a wide range of quasi-periodic profiles of a variable oscillation period and for local zones of bend-torsion emerging at the surface. These zones appear as stress concentrators of different scale levels and generate all the types of stress-induced defects at the surface.
